Can one ever be "done" in this hobby?

Thank you folks.  After reading this thread, i put my ear up to the various drivers.....hissy noise in The right Heil AMT tweeter/mid.   Appears to be from my ESS 2142 crossover.  And the quest goes on.  Did my due diligence, unplugged the IC to amp, noise gone.  IC connected to amp but not the ESS xover still no noise.  Unplugged the input to the ESS xover and the noise stayed.

Correction.  The ESS xover is model 2241.  Question for Millercarbon or Geofkaitt or any one.  Considering a tube amp to run the ESS Heil AMT.  I listen at mostly moderate levels.  Current amp is Parasound Zamp.3 at 35w per channel.  There is a Wavebourn on E for 800+shipping, but only 6 watts.  Is that enough power?

Thank you geoffkait.
